Answer:

Second order

Explanation:

Given that:

When the reaction A → B + C is studied, a plot 1/[A]t vs. time gives a straight line with a positive slope.

From the integration method for the second order of reaction.

Suppose that:

rate = k₂[A]²

∴

$\dfrac{1}{A}=\dfrac{1}{A_0}+k_2t$

Therefore, a plot of the linear function $\dfrac{1}{A}$ versus t will be linear with a positive slope k₂ and the intercept on the concentration axis will be $\dfrac{1}{A_o}$

The linear plot for a second order reaction can be seen in theimage attached below.
